Pull creation of GrPipeline explicitly into the Ops' onExecute methods

This is a first step towards pulling the creation of the GrProgramInfos explicitly into the Ops' onExecute methods. We need this behavior so programInfo creation can be moved forward to onPrePrepare.

For now, pipeline creation is a static member on GrSimpleMeshDrawOpHelper so GrPipeline creation can be bottle-neckedOps for Ops that don't use the helper. In some future world CreatePipeline could become non-static to reduce some of the duplicate code.
